		<h1>[name]</h1>

		<p class="desc">A loader for loading a <em>.svg</em> resource.<br >
		<a href="https://en.wikipedia.org/wiki/Scalable_Vector_Graphics">Scalable Vector Graphics</a> is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation.
		</p>

		<h2>代码示例</h2>

		<code>
		// instantiate a loader
		const loader = new SVGLoader();

		// load a SVG resource
		loader.load(
			// resource URL
			'data/svgSample.svg',
			// called when the resource is loaded
			function ( data ) {

				const paths = data.paths;
				const group = new THREE.Group();

				for ( let i = 0; i < paths.length; i ++ ) {

					const path = paths[ i ];

					const material = new THREE.MeshBasicMaterial( {
						color: path.color,
						side: THREE.DoubleSide,
						depthWrite: false
					} );

					const shapes = SVGLoader.createShapes( path );

					for ( let j = 0; j < shapes.length; j ++ ) {

						const shape = shapes[ j ];
						const geometry = new THREE.ShapeGeometry( shape );
						const mesh = new THREE.Mesh( geometry, material );
						group.add( mesh );

					}

				}

				scene.add( group );

			},
			// called when loading is in progresses
			function ( xhr ) {

				console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

			},
			// called when loading has errors
			function ( error ) {

				console.log( 'An error happened' );

			}
		);

		<h2>Constructor</h2>

		<h3>[name]( [param:LoadingManager manager] )</h3>
		<p>
		[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
		</p>
		<p>
		Creates a new [name].
		</p>

		<h2>Properties</h2>
		<p>See the base [page:Loader] class for common properties.</p>

		<h2>Methods</h2>
		<p>See the base [page:Loader] class for common methods.</p>

		<h3>[method:null load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
		<p>
		[page:String url] — A string containing the path/URL of the <em>.svg</em> file.<br />
		[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives an array of [page:ShapePath] as an argument.<br />
		[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes.<br />
		[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
		</p>
		<p>
		Begin loading from url and call onLoad with the response content.
		</p>

		<h2>Static Methods</h2>

		<h3>[method:Array createShapes]( [param:ShapePath shape] )</h3>
		<p>
		[page:ShapePath shape] — A ShapePath from the array of [page:ShapePath], given as argument in the onLoad function for the load function of [page:SVGLoader].<br />
		</p>
		<p>
		Returns one or more [page:Shape] objects created from the [param:ShapePath shape] provided as an argument in this function.
